0090 --  task is created and started, it will preempt this task and

0092 --  initialization is completed, the timer is started and the first
0093 --  preemptive MESSAGE_QUEUE_SEND is executed.

0104 --  DESCRIPTION:
0105 --
0106 --  This RTEMS task is the highest priority task in the system.
0107 --  It performs a blocking blocking MESSAGE_QUEUE_RECEIVE.  It is
0108 --  the last test task created and started.  Thus it is the last
0109 --  task to be enqueued waiting for a message and the last task
0110 --  to receive the message.  Once it receives the message, it
0111 --  stops the timer and reports the execution time for a
0112 --  preemptive MESSAGE_QUEUE_SEND.
